Abstract

U ovom diplomskom radu promatramo izboj s dielektričnom barijerom te različite načine njegove primjene u industriji. Posebnost ove vrste izboja je lakoća rada pri atmosferskom tlaku te kombiniranje korisnih svojstava netermalne plazme. Jedna od velikih prednosti izboja s dielektričnom barijerom je laka promjena dimenzija- prigodan je za rad u malim laboratorijskim reaktorima, no i u velikim industrijskim instalacijama. Industrijske primjene su stvaranje ozona, kontrola onečišćenja, modifikacija površine, CO2 laseri, ekscimerske lampe, plazma ekrani. Ovisno o primjeni i uvjetima rada izboj može imati vlaknastu strukturu ili raspršen izgled. U ovom radu detaljno je opisana povijest izboja u plinovima, fizičke osnove i svojstva standardnog i izboja s dielektričnom barijerom te moguće primjene.

Abstract (english)

We examine dielectric barrier discharge and its use on a large industrial scale. A prominent feature is the ease of atmospheric-pressure operation and the use of nonequilibrium plasma properties. One of the great advantages is simple scalability from small laboratory reactors to large industrial installations. Industrial applications include ozone generation, pollution control, surface treatment, high power CO2 lasers, ultraviolet excimer lamps and flat large-area plasma displays. Depending on the application and the operating conditions the discharge can have pronounced filamentary structure or fairly diffuse appearance. History, discharge physics and their applications are discussed in detail.
